Overweight and obese patients with osteoarthritis (OA) experience more OA pain disability than who are not overweight. This study examined the long-term efficacy of a combined coping skills training (PCST) lifestyle behavioral weight management (BWM) intervention in overweight patients. Patients (n=232) were randomized to 6-month program of: 1) PCST+BWM; 2) PCST-only; 3) BWM-only; or 4) standard care control. Assessments pain, physical (Arthritis Impact Measurement Scales [AIMS] disability,...
Jones and proximal diaphyseal fractures of the fifth metatarsal are in close anatomic proximity often difficult to differentiate. We determined whether it is necessary differentiate between these two diagnoses. Retrospectively, diagnoses were identified radiographically using an accepted classification scheme. Initial management nonoperative; however, intramedullary screw fixation performed for competitive athletes, or others with displaced fractures, delayed union nonunion. Outcomes...
Background: Excessive tibiotalar malalignment in the coronal plane has been considered by some to be a contraindication total ankle replacement. The purpose of present study was compare clinical outcomes and physical performance measures according preoperative alignment. Methods: One hundred three patients undergoing replacement were grouped Seventeen had an excessive deformity (>15° varus or valgus), twenty-one moderate valgus alignment (5° 15° twenty-seven varus), thirty-eight neutral (<5°...
In this article, I focus on the intonation patterns of Turkish-German bilinguals to discuss within context language contact and variation. The intonational variance involves realization terminal rises as produced by second- third-generation living in Germany. These speakers produce two phonetically, phonologically, pragmatically distinct rises, which differ from what is typically reported for German monolinguals. primary phonetic differences between include relative alignment slope rise,...
Background: Little is known about the efficacy and durability of total ankle arthroplasty (TAA) in younger patients. The purpose this study was to determine effect age on clinical, radiographic, patient-reported outcomes patients with end-stage arthritis treated TAA using modern prostheses. Methods: Patients who underwent primary from June 2007 July 2011 were prospectively enrolled study. Three hundred ninety-five consecutive reviewed a mean follow-up 3.5 years (range, 2-5.4 years). divided...
The assessment of loading during walking and running has historically been limited to data collection in laboratory settings or with devices that require a computer connection. This study aims determine if the loadsol®—a single sensor wireless insole—is valid reliable method assessing force. Thirty (17 male 13 female) recreationally active individuals were recruited for two visit where they walked (1.3 m/s) ran (3.0 3.5 at 0%, 10% incline, decline, visits approximately one week apart. Ground...
Humans are remarkably efficient at parsing basic linguistic cues and show an equally impressive ability to produce parse socially indexed from the language(s) they encounter. In this review, we focus on ways in which questions of justice equality linked these two abilities. We discuss how social theorized become correlated with each other, describe listeners' perceptual abilities regarding cognition, address how, context abilities, language mediates individuals’ negotiations institutions...
Background: The current literature is not clear regarding the best method of determining medial longitudinal arch (MLA) height. Differences in MLA height can significantly alter lower extremity biomechanics; therefore, an accurate and reproducible assessment essential for clinical evaluation future research. goal this project was to determine reliability common measurement techniques. Methods: Foot length, truncated foot navicular height, dorsal footprint indices were obtained from healthy...
Groin pain is a common cause of athletic disability and often involves the adductor longus. A complaint patients with groin problems while preparing to kick ball. The purpose this study was examine muscle length activation longus kicking soccer Three-dimensional joint positions were obtained from 15 National Collegiate Athletic Association (NCAA) Division 1 male players during maximal effort kicks. Musculoskeletal modeling techniques incorporating position attachments used estimate beginning...
Background: Similar subjective outcomes have been reported for tenotomy or tenodesis of the long head biceps. Few studies on postoperative strength and endurance. Hypothesis: Biceps results in superior outcomes, strength, endurance compared with tenotomy. Study Design: Cohort study; Level evidence, 3. Methods: Participants completed isokinetic testing elbow flexion supination operative nonoperative sides a minimum 2 years after biceps tenodesis. Modified American Shoulder Elbow Surgeons...
Several fixed-bearing total ankle arthroplasty systems are available in the United States. We report on early clinical results of largest known cohort patients States who received a Salto Talaris replacement for treatment end-stage arthritis ankle.We prospectively followed sixty-seven with minimum follow-up two years. Patients completed standardized assessments and underwent physical examination, functional assessment, radiographic evaluation preoperatively at six weeks, three months, months...
Background: Anterior cruciate ligament injuries (ACL) commonly occur during jump landing and cutting tasks. Attempts to land softly with greater knee flexion are associated decreased ACL loading. However, their effects on performance unclear. Hypothesis: will decrease peak posterior ground-reaction force (PPGRF) extension moment at PPGRF compared a natural stop-jump side-cutting initial ground contact increase both In addition, techniques stance time lower extremity mechanical work as well...
Asymmetries in sagittal plane knee kinetics have been identified as a risk factor for anterior cruciate ligament ( ACL ) re‐injury. Clinical tools are needed to identify the asymmetries. This study examined relationships between kinetic asymmetries and ground reaction force GRF during athletic tasks adolescent patients following reconstruction ACL‐R ). Kinematic data were collected stop‐jump task side‐cutting 23 patients. Asymmetry indices surgical non‐surgical limbs calculated variables....
Total ankle replacement (TAR) continues to grow as an alternative arthrodesis for patients who suffer from end-stage arthritis. The purpose of this study was examine changes in gait mechanics before surgery 1 and 2 years after received a fixed-bearing TAR.Fifty-one with primary TAR no complications requiring further were identified database enrolled non-randomized study. Subjects examined preoperatively, at postoperatively. Three-dimensional joint ground reaction forces (GRF) collected...
There has been a continuing increase in the use of total ankle arthroplasty for treatment end-stage arthritis. Our aim was to determine clinical, radiographic, and functional outcomes arthroplasties done with prosthesis modular intramedullary stem referencing align tibia.A consecutive series patients who underwent INBONE Total Ankle Replacement from June 2007 December 2010 were enrolled this study. Pain patient-reported function assessed visual analog scale (VAS) pain, American Orthopaedic...
Clinically feasible methods for quantifying landing kinetics could help identify patients at risk secondary anterior cruciate ligament injuries. The purpose of this study was to evaluate the validity and between-day repeatability loadsol insole during a single-hop bilateral stop-jump. Thirty healthy recreational athletes completed seven single-hops stop-jumps while simultaneous (100 Hz) force plate (1920 measurements were recorded. Peak impact force, loading rate, impulse computed dominant...
No standardized return-to-activity or sport guidelines currently exist after anterior cruciate ligament (ACL) reconstruction. Isokinetic testing and unilateral hop testing, which have construct validity, are often used to make the determination of when a patient is ready return sport. Neither these measures has been reported be predictive subsequent injuries.To compare performance on 2 functional tests ACL reconstruction patients released activity versus those who not based clinical...
